  • Patent number: 9365472
    Abstract: A method for producing 1234Z from 1234E while generation of 245fa as a byproduct is suppressed. The method for producing cis-1,3,3,3-tetrafluoropropene includes putting trans-1,3,3,3-tetrafluoropropene into contact with a catalyst. The trans-1,3,3,3-tetrafluoropropene is put into contact with the catalyst at a reaction temperature of higher than or equal to 200° C. and lower than or equal to 550° C. for a contact time of longer than or equal to 0.01 seconds and shorter than or equal to 500 seconds.
